find the value of 'x' 9x=27
1. find the value of 'x' 9x=27
9x = 27
divide the both sides by 9
9x ÷ 9 = 27 ÷ 9
x = 3
so , the value of x is 3
9x=27
×=27/9
×=3
the value of x is 3
2. Find the value of x if 2x+10 = 76.
2x + 10 = 76
2x = 76 - 10
2x = 56
x = 28
3. if x² + 5x = 5 find the value of x³+6x²
Jawab:
Penjelasan dengan langkah-langkah:
x² + 5x = 5
i) x² = 5 - 5x
ii) x(x² + 5x) = 5(x)
x³ + 5x² = 5x
x³ + 6x² = x² + 5x²+ x²
x³ + 6x² = (x² + 5x²)+ ( x² )
x³ + 6x² = (5x)+ (5 - 5x)
x³ + 6x² = 5x + 5 - 5x
x³ + 6x² = 5
4. if x²-7x+2=0 calculate the value of (x²-9/x²) is..
x²=7x-2
so (x²-9/x²) =((7x-2)²-9/(7x-2)²)
=49x²-28x+4-9 / 49x²-28x+4/9
=49x²-28x-5/(7x-2)²
=(7x+1)(7x-5)/(7x-2)²
5. Find the value of X
Jawab:
47
Penjelasan dengan langkah-langkah:
1.
Garis lurus:180
Sudut sebelah 117:
180-117:
:63
karena bersebrangan maka :
X:180-(30+40+63)
x:180-133
x:47
[tex]\left[\begin{array}{c}KHAZZAMY\\MATH\\BRAINLY\end{array}\right][/tex]
Jawab:47°
Penjelasan dengan langkah-langkah:How to find the value of X:
Eng:
Total degrees of circle: 360°
If we look at the total with the radius under it is half the circle or 180°
And those that are not marked with X are equal to 63°
(because 117° - 180° = 63°)
So.. to find the value of X is:
63° + 30° + 40 = 133°
180° + 133° = 47°
Indo:
Derajat total lingkaran: 360°
Jika kita melihat total dengan juring di bawahnya adalah setengah lingkaran atau 180°
Dan yang tidak bertanda X sama dengan 63° (karena 117° - 180° = 63°)
Jadi .. untuk mencari nilai X adalah:
63° + 30° + 40° = 133°
180° + 133° = 47°
Semoga membantu;)
I hope these helps..
6. Given that 27 - 2x < 8, find (a) the smallest value of x, (b) the smallest integer value of x.
(a) 27 - 2x ≤ 8
-2x ≤ -19
x ≥ 19/2
x ≥ 9,5
(b) smallest integer value of x? I'm sure it's 10 .. (maybe ¯\_(ツ)_/¯)

8. find the value of x + y !
Jawab:
Penjelasan dengan langkah-langkah:
2x + y = 180 (i)
(x-19) + y + 90 = 180 (ii)
------------------------------
2x + y = 180
(x-19) + y = 90
---------------------- (eliminasi)
2x - (x-19) = 90
x +19 = 90
x = 90-19 = 71
---------------------
2x + y = 180
2(71) + y = 180
142 + y = 180
y = 180-142 = 38
x + y = 38 + 71 = 109
9. find the value of x
Jawab:
x = 11
Penjelasan dengan langkah-langkah:
9x + 6 + 7x - 4 + 7x + 5 + 5x - 4 + 4x + 5 = 360
32x + 8 = 360
32x = 360 - 8
32x = 352
x = 352 : 32
x = 11
Jawaban:
11
Penjelasandenganlangkah-langkah:
9x + 6 + 7x - 4 + 7x + 5 + 5x - 4 + 4x + 5 = 360 (<'s at a point)
9x + 7x + 7x + 5x + 4x = 360 - 6 + 4 - 5 + 4 - 5
32x = 352
x = 352/32
x = 11
⁂ x = 11
so, the value of the x is 11.
Semoga membantu. maaf kalo salah,
Have a lovely day ~
10. find the value of x
Jawaban:
10
Penjelasan dengan langkah-langkah:
11x + 7 + 6x + 3 = 180
17x + 10 = 180
17x = 180 - 10
17x = 170
x = 170 : 17
x = 10
Jawaban:
10°
Penjelasan dengan langkah-langkah:
11x + 7 + 6x + 3 = 180
17x + 10 = 180
17x = 180 - 10
17x = 170
x = 170 ÷ 17
x = 10° ✔

Kalo membantu rate dan like jawabanku.
Have a nice day :)
11. Find the value of x!
Jawaban:
angle a = 50°
angle b = 70 °
angle c=x
angle a + angle b + angle c = 180°
50°+70°+x=180°
120°+x=180°
x=180°-120°
x=60°
Hence, option (a) is the right answer.
HOPE IT HELPS YOU.....
12. if g(x) = √4x-1 and g(x) = 5, find the value of x
Penjelasan dengan langkah-langkah:
[tex]g(x) = \sqrt{4x - 1} \\ 5 = \sqrt{4x - 1} \\ {5}^{2} = ({ \sqrt{4x - 1} })^{2} \\ 25 = 4x - 1 \\ 26 = 4x \\ x = \frac{26}{4} = \frac{13}{2} [/tex]
atau soalnya begini:
[tex]g(x) = \sqrt{4x} - 1 \\ 5 = \sqrt{4x} - 1 \\ 6 = \sqrt{4x} \\ {6}^{2} = { \sqrt{4x} }^{2} \\ 36 = 4x \\ 9 = x[/tex]
jawabannya tergantung soalnya, karena soalnya kurang jelas.
13. If x²-y²=6 and x-y=2, find the value of (x+y)²
x² - y² = 6
(x - y)(x + y) = 6
2(x + y) = 6
(x + y) = 3
So, the value of (x + y)² :
= 3²
= 9
14. if x² + 5x = 5 find the value of x³+6x²
✇ Algebra_
-
If x² + 5x = 5 , The value of x³ + 6x² is 5
DISCUSSION:
Note that :
x³ + 6x² = x(x² + 6x)
x³ + 6x² = x[(x² + 5x) + x]
x³ + 6x² = x(5 + x)
x² + 6x² = x² + 5x
So , we get x² + 6x² = x² + 5x = 5

15. Find The value of x 77.5% of x =17
Jawaban:
77,5/100 x = 17
x= 17× 100/77,5
x= 68/3,1
16. if x - y = √6 and x²+y²=4 find the value of xy
Jawaban:
x - y = √6
(x - y)² = (√6)²
x² + y² - 2xy = 6
(x² + y²) - 2xy = 6
4 - 2xy = 6
2xy = 4 - 6
xy = -2 ÷ 2
= -1

20. find the value of x
1) 3x + 6x membentuk sudut siku siku maka:
3x + 6x = 90°
9x = 90°
x = 90°/9
x = 10°
2) 2a + 3a + 20 = 180°
5a + 20 = 180°
5a = 180 - 20
5a = 160
a = 160/5
a = 32
3) z = 120°
y = x = 180-120
y = x = 60°
4) 4/6 = 6/a
a = 6×6/4
a = 9 cm
semoga membantu
